Specification of Letters Patent.

Application filed April 19,1906- Serial No. 312,560-

To all whom it may concern.-

Be it known that 1, JOHN MURPHY, a citi- Zen of-the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification.

My invention relates to an improvement in railway-ties, and particularly to that class of ties which are formed of a suitable composition.

This invention is designed as an improvement upon the railway-tie shown and described in Patent No. 758,927, issued to me upon May 3, 1904.

It was found upon experiment that it was difficult to mold a body as large as a railwaytie of clay, owing to the fact that it was liable to crack and warp before so large abody could dry. To obviate this difficulty, I have devised the tie shown in the accompanying drawings, wherein- Figure 1 is a side elevation of a railroad-tie constructed in accordance with the invention, showing a pair of rails in section thereon. Fig. 2 is a plan view of the parts shown in Fig. 1. Fig. 3 is a longitudinal vertical section of the tie upon line x :1; of Fig. 1, and Fig. 4 is a transverse vertical section of the tie.

Like numerals designate corresponding parts in all of the figures of the drawings.

It is the objectof the present invention to provide a railway-tie made in sections and aving improved means for binding said sections together, whereby said sections are of such size that they will readily dry without cracking or warping.

In the accompanying drawings the numeral 5 designates the central section of the tie, while the numerals 6 designate the outer sections of the tie. All of these sections have a channel 7 formed longitudinally therethrough, while molded in the sections 6 are wooden blocks 8. Shoulders 9 are formed upon the sections 6 and serve to prevent lat eral movement of the rails 10 by en aging the sides of the bases 11 thereof. Res ient cushiom'ng-strips 12 are inserted beneath the base-flanges the same. The ends of the sections are recessed, as at 13, and when it is desired to secure said sections together to form a complete tie said recesses are filled with cement 14.. Tie-rods 15 are then passed longitudinally through the channel 7, said tie-rods of the rails and serve to cushion having heads 18 upon one end thereof, which rest, when the parts are in their assembled position, against a plate 19, which closes one end of the channel 7. Said channel 7 is then filled with grout, (indicated at 20,) after which a plate 21 is placed in position to close the other end of the channel 7 and nuts 22 arethreaded upon the ends of the tie-rods to bind all of the parts together. These tierods are made in two sections, said sections being joined by a hook-and-eye joint at 25. This results in imparting a limited flexibility to the tie as a whole and reduces the strain upon the rolling-stock which passes over the track.

I The scarcity of lumber renders the old wooden tie very expensive, and a tie which may be made from a suitable clay has long been sought; but, as before stated, the difficulties met with in drying clay bodies of the size of a railroad-tie have rendered it impossible to produce a satisfactory tie of this character. Byvirtue of the construction herein set forth I amenabled to make a tie of this character without having it crack or warpin the making.

While the elements shown and described are well adapted to serve the purposes for which they; are intended, it is to be understood that the invention is notlimited to the precise construction set forth, but includes within its purview such changes as maybe made within the scope of the appended claims. 1;

What I claim is 1. A railroad-tie formed of a plurality of hollow moldedsections, means for binding all of saidsections together end to end and a filling of plastic material adapted to harden or set, in said hollow sections.

2. A railroad-tie formed of a plurality of molded sections having channels formed theretln'ough, means for binding said sections together end to end, and a filling of grout in said channels.

3. A, railroad-tie comprising a plurality of molded sections, and flexible members for binding all of said sections together end to .end.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN MURPHY.
